Specification of Letters Patent.

Patented May 28, 1907.

1'0 all whom it may concern:

Be it known that I, ERNEST A. FALLER, a citizen of the German Em ire, residing at New York, in the county 0 New York and State of New York, have invented certain new and useful Improvements in Electrotypes or the Like, of which the following is a specification.

The invention forming the subject-matter of this application relates to the art of printing, and more especially to multi-color rinting for various purposes, but particular y for advertising.

The principal desideratum in an advertisement is, of cours that'it should attract the attention of the reader. This becomes all the more important if the advertisement is contained in a great mass of other advertising matter, such as is the case with a newspaper or similar publication. One of the most effective ways to attract the eye of a reader to an advertisement is to have something printed therein in a color which con trasts with the rest of the.advertisement, and

I am well aware that advertisements inhave been the cause of preventing its adop- 1 tion generally, and more particularly for advertising purposes in daily newspapers, mag-' azines and other publications printed 1n large quantities upon presses designed to print in one color only.

The prime object of this invention is to provide such means that multi-color printing may be effected on presses now generally in use for printing in onecolor without in any way altering such presses and with no more trouble nor loss of time than it takes to print in one color, whereby multi-color printing in such publications as above mentioned is made commercially practicable. This I accomplish by the'construction and use of an electrotype or the like having a movable design or printing surface, means within the said electrotype or the like operative by an v.impression receiving surface but non-operative by the inking mechanism of the press to effect the movement of such printing surface or surfaces to cause the same to print,

the said movable printing surface or surfaces being inked from within the electrotype. ,The alteration is, therefore, made in the electroty e or the like and not in the press.

Ot er novel features of my invention will be hereinafter described and more particularly pointed out in the claims.

When I refer to an electrotype or the like, I intend to include not only what is ordinarily called .an electrot e in the printers art, but also any kind 0 wood-cut, engraving, stereot e half-tone, or any other negative or th like adapted to make an imprint or impression on paper for the purpose of duplication.

In order to more fully describe my invention, reference will be had to the accompanying drawings, wherein:

Figure 1 is a longitudinal section through an electrot e constructed according to my invention; ig. 2, a top plan view of the same as seen from the bottom; Fig. 3 a fragmentary top plan view; Fig. 4, a perspective view artly in section, of the mechanism of the eibctrotype; Fig. 5, an enlarged detail view of the assembled mechanism of the same; Fig. 6, a detail view of the ink receptacle, and Figs. 7 and 8 are diagrams illustrating the operation of the electroty e, Fig. 7 showing it in the act of inking; and F ig. 8 in the act of printing. v Similar parts are represented by similar numerals throughout the several views.

The body of the electrotype consists preferably of a casting 1, hollowed out to save weight and provided with strengthening ribs 2, to preserve rigidity. The top of the casting, which is preferably integral with the body portion thereof, forms the rinting surface and may have thereon in re ief or otherwise any desired design 28. It is possible, however, to construct the body containing any suitable electrotype or cut on the flat top of the same very much in the same manner as is now done in the case of wood-backed electrotypes.

Ordinary electrotypes consisting of a metal to and the backing of Wood may be employe but I prefer to make the entire electrotype out of metal in very much the same manner as the so-called patent matteris made in the practice of small newspapers, namely, the entire column or part of the column is cast type-high, so that no wood backing is required. The reason that this is the mechanism independently and fasten thereto two levers 5 and 6.

preferable is that in this manner, by the use of a special mold, all the necessary bearings, cavities, etc, can be provided for in the backing of the electrotype.

The casting carries two pro'ections 3 for a purpose hereinafter mentione In the cast- 1ng is fulcrumed a shaft 4 having fastened On the extreme ends of these levers is fastened a rocking frame 8 by means of the fulcra 7. This frame is free to oscillate on the said fulcra, and carries two projections 9 and 10. A spring 11 made fast to the body of the electrotype, as shown, maintains all parts so far mentioned in the position shown in Fig. 1.

Carried near the upwardly extending ends of the projection 3 is a shaft 12, forming a pivoted sup ort for a lever 13. This lever 13 is provl ed at one end with a circular opening to accommodate an ink reservoir, which will be described later. The other end of this lever 13 is bifurcated as at 14, to engage a pin 15. This pin 15 is carried by two short arms 16 and 17, fastened to the sh aft 4.

It will be readily seen from an inspection of the drawings that a downward movement of the levers 5 and 6 will result, through the medium of the mechanism just described, in an upward movement of that end of the lever 13 which is provided with a circular opening above referred to. The spring 11, however, is bent in such a manner as tobear against the frame 8, and in two points 18 and 19, located res ectively at opposite sides. of the fulcra 7. The result is, therefore, that not only is the frame 8 pressed upward, but it is also maintained in a horizontal position. It follows from the foregoing that the pierced end of the lever 13 is therefore normally in its lowest position.

In the circular opening of the lever 13 is carried the ink reservoir, which is shown in detail in Fig. 6. It consists, among other parts, of a cylinder 20, provided at its lower end with a screw cap 21. A piston 22 fits inside the cylinder ink-tight, and a spring 23 surrounds the outside of the cylinder and acts as an equalizer and buffer for the impression. A spring 24 normally presses upon the piston 22 as shown. In the top of the ink reservoir is a packing of orous material 25 and above this, a disk 0 very fine wire gauze 26, which forms the printing surface. The tension of the spring 24 is so re ulated that it .will at all times keep the pac ing 25 saturated with ink without, however, forcing the same through the top 26.

The inside of the cylinder 20 is filled with an inking preparation of any suitable consistency and referably' of a color contrastin with or di ering from that of the regular coTor used in the press. The amount of ink forced through by the piston 22 can be regulated both by the consistency of the ink and the pressure of the spring 24. Either or both of these will,-of course, be re ulated so as to provide a ood impression anr leave the right amount of ink on the paper in any instance. I have found in practice, however, that it is not necessary to actually force the ink through the porous top, in all cases, by the pressure of the spring, as the top 26 embeds itself sli htl in the paper during the socalled we 1 of the press, and when the paper recedes, a small vacuum is formed, causin a small quantity of the ink to ooze throug the top 26, thereby providing a supply for the next impression.

From an inspection of the drawings it will be seen that either of the projections 9 or 10 may be de ressed without causing any appreciable or e ective movement of the levers 5 and 6, and, consequently, of the cylinder and printing surface 26. If, however, the two projections 9 and 10 are depressed simultaneously, or if one is held down while the other is depressed, they will cause the levers 5, 6 to swing on their fulcra 4 against the pressure of the spring 11, and consequently bring the top or printing surface 26 of the cylinder 20 up to the printing height. I shall now show how these projections 9, 10 are operated to cause the printing surface to print, and how the said projections are rendered non-operative by the ink rollers of the press, whereby the passage of such ink rollers over the electrotype does not effect an inking of the movable printin surface. For this purpose, reference will Iie had to Fi s. 7 and 8, which illustrate diagrammatical y the operation of the device in a press. Fig. 7 shows the bed of a printing press 29, the ink rollers '30. 31 and the form 32, containing, among other matter, the electrotype. It is immaterial whether the rollers or the form 32 move on the bed. Assuming that the form 32 is sta tionary and the rollers move in the direction of the arrow, it will be seen that the ink roller 30, on passin over point 10, will depress this point to t ie printing level but will not cause any actuation of the levers 5, 6. The only result is, therefore, to raise the point 9 still farther above the printing level to an extent equal to the depression of point 10. If now the ink roller proceeds farther so as to strike against point 9, the reverse will happen, namely, projection 9 will be depressed, while rojection 10 is elevated to the same extent. The roller having left projection 10, there is no obstacle in the way to revent the said rojection from being raised It will readily lie seen, therefore, that if there is more than one ink roller the above operation will repeat itself as long as the distance between projections 9 and 10 is less than the diameterof the ink rollers employed, since at no time then can one ink roller be on projection 9 while the next is on projectionlO.

From the foregoing it will be seen that it matters not how many times the ink rollers pass over these projections, the auxiliary printing surface 26 will not be brought into contact with such rollers, for the reason that each time an ink roller passes over a point above the auxiliary printing surface, the roller finds such surface below the general surface of the electrotype. It is, therefore, plain that while all those parts. of the electrotype which are type-high take ink from the rollers, the printing surface 26 does not.

When the printing cylinderor platen comes into engagement with the rinting surface of.

the electrotype, this will slmultaneously engage both projections 9 and 10, with the result that the frame 8 carrying them, and the ends of the levers 5, 6 pivoted thereto will be carried downward, im arting limited rotation to the shaft 4. Tliis'will cause the rod 15 to send the end 14 of the lever 13 down, and the other end carrying the cylinder'up, thus sending the printing surface 26 against the paper and printing on such paper the de-,

In the case of a cylinder press, the con ditions are slightly different, as the laten in this case is cylindrical instead of at. As the curvature of this cylinder, shown in Fig. 8 in dotted lines, however, is so great in comparison with that of an ink roller, it also will cause practically simultaneous and complete depression of the projections 9 and 10, andconsequently cause the auxiliary surface 26 to make its impression.

The action of a rotary press such as is now used for large news apers diflers again from those so far 'descrl ed, as the electrotype used therein instead of having a flat surface must be curved; but the same relation of our vature between the printing cylinder and the ink rollers obtains, so thatan auxiliary impression can still be made. Since in the case of these rotary presses, the whole matter contained on a page is'printed from a curved stereotype plate,in order to use myinvention with such presses, a special mold must be provided, which, in the casting of the stereoty e plate, leaves the necessary recesses for t e accommodation of my electrotype which itself must have a curvature to conform to that of the curved stereotype late.

The three cases above re erred to cover practically all methods em loyed at the resprinting ent, time in printing, but t is invention ends I itself to many other uses which it is not necessary to-referto here specifically.

This electrotype is intended to be indiscriminately used with different kinds of matter in all kinds of printing presses. Now it may be that sometimes the electrotype has such a positionin the chase or form that the ink rollers pass over it in a direction parallel to its longer sides, and at other times in a direction arallel to its shorter sides; in other wors, with the present methods of rinting, there are two positions possible or the electrotype to assume in relation to the ink rollers in the press, namely, it can be put in the form so t at either thelong or the short side is parallel with the axes of the ink rollers. It is consequently necessary that the lever 8 should operate in the manner previously described irres ective of the direction in which the ink ro lers pass over the projections 9 and 10. This is accomplished y lacing the rojections 9 and 10 diagonal yacross the ace of and equi-distant from the center of the auxiliary printing surface of the electrotype. Moreover, it is preferable that the auxiliary, printing surface should always be included between the diagonal projections 9 and 10, forwhile this is not essential in using the electrotype in a platen ress, it is essential when in use with a cylin er press. This will be readily understood by referring to Fig. 8 of the drawings, where the cylinder of a cylinder press is indicated by dotted lines. If the projections 9 and 10 were not on both sides of the auxiliary printing surface, the cylinder would pass both ofthese points before or after reaching the auxiliary printing surface,an'd consequently the device would not for practically all the publications of smaller towns and cities. The cause of this limitation is the comparatively restricted size of the ink reservoir 20. The size of this reservoir is limited by the depth of the electrotype, and as electrotypes areusually of a standard depth (namely, of an inch), I have. found that the ink reservoir 20 cannot have a greatertotal height than i of an inch. Moreover, the diameter of the reservoir must preferably bear a certain proportion to its ength, or rather to the axial length of the piston, or otherwise the latter Wlll not be guided properly. Thus I have found that it is impracticable in the form shown to make the diameter greater than of an inch, the piston itself preferably having an axial ever a sma s1ons 1s required and the quality of the impression 1n the contrasting color is of minor &

conse uence, it will serve its purpose. When I spea of the quality of the impression, I

. pair of ugs carried have, of course, reference to the varying amount of ink deposited upon the paper,

. thereby causing a variation n the exact outline of the fi re or design rinted, in the contrasting in but for all or inary purposes the work done is quite good enough.
